HEAT-RADIATING DEVICE.

T 0 all whom t may concern.:

Be it knownthat I. EUGENE G. MGGLAUF- LiN. a citizen of the United States, residing at Portland, in Vthe i county of Multnomah and State of Gregon, have invented a new and usefullmprovement in Heat-Radiating Devices, of which the following is a specification, reference. being had to the accompanying drawings. l

My invention relat-es to heating devices The object of `my invention is to provide a heating device for a dry-kiln arrangedin a manner whereby substantially the same body of air in the kiln may be caused to circulate in heated condition 'for drying purposes and when charged 4or saturated with eXudations -from the drying materialtobe thereafter quickly cooled to deposit its .said content and be again thereafter used for l drying. Also a `convenient arrangement of the sheeting of said wall.

the heating device whereby it may be quickly installed and repaired with economy. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form' a part hereof.

Fig. 1 is a cross sectional elevation of the kiln. v

Fig. 2 is a plan view of tracks and a section of piping below same.

Fig. 3 is a sectional elevation of a longitudinal part of the kiln near the ceiling on the'line 3-3 in Fig. 1.

Fig l is an enlarged sectional view of vertical spacing wall or partition.

p Like characters refer to like parts in all the views.

A rectangular structure of desired di1nensions is provided'. lt is intended that the wooden construction shall be of culled material for economy thereof. A. `foundation preferably of artificial stone, is placed. A low, wooden base wall 5 is erected on the foundation, and above this the outer walls 5 are of thin metal, preferably corrugated material. 0n the inside of the vertical studding which supports the walls, a wooden spacing wall 6 extends from a desired height above the foundation to a desired distance from the ceiling. This is to make hollow walls for the distance indicated. rlhe wall 6 is of double thickness, with a material 7, which is a non-conductor of heat, between The ceiling 8 i Specification of Letters Patent.

is of the same construction as the wall 6. 1n the forward end of the structure for a short distance rearwardly, a part of the walls 6, indicated as 9 in Fig. 3, extends upwardly to a joining position with the ceiling S. Longitudinally of the structure, a series of track rails 10 are secured upon frames 11 below. `Agheat supply pipe 12 extends from an outside heating source, within the structure to a connection with a pipe 13 extending at a convenient distance from and parallel-with one wall 6. On the opposite side a pipe la extends longitudinallyalongthe iioor of the structure parallel with, at a little distance from, and below the bottom of the opposing wall 6.v rThe pipe 14C has a discharge pipe 15 extending from Ait and without the structure. A series of pipe batteries 1G are arranged one above the other between the rail tracks and floor. Fach of the batteries h asl'aseries of horizontal pipes 17 extending from connections with the respective pipes 13 and 14 inwardly at an angle to a connection with each other at their opposite ends. Joining means 18 are placed in the pipes 17 tov facilitate placing them in position and taking them apart. Drain outlets 19 are arranged from below the hollow wall space outwardly of the structure. Trucks 2O are shown in position on the tracks, bearing material in the process of drying.

lt will now be seen that when the tracks are filled with material laden trucks and .heat is admitted to the pipe system, the

heated air which rises from below the series of trucks in the forward end cannot follow a. course over the tops of the inside walls 6, as they are there joined to the ceiling as shown in Fi 3, and the air remains longer in that portion of the structure, thereby supplying a non-circulating hot air medium which provides a steadier heat. Thus the liquids in the material are drawn therefrom and absorbed by the heated air in a manner to prevent the common checking or case hardening therein. The material on the first series of trucks introduced into the structure will always have this first treatment. Thereafter the trucks are pushed forwardly and in the remaining part of the structure the heated air follows a course upwardly through the material, thence being deflected by the ceiling over the walls 6 and downwardly through the hollow wall spaces between the walls 5 and 6. The

described.

air, being then charged with the liquids or substances absorbed from' the ldrying material, engages the thin outer wall 5,', which being cooled 'by the outer atmos-` phere, the absorbed liquids,'etc., are thereupon condensed and trickle downwardly, to escape through the outlets 19, while the same lair, with its partial heat, continues in and about the heating pipes, and follows the same circulating course as shown by the arrows in Fig. l, with the same results as It is` also intended that the pipes 17 shall be inclined in a manner lto allow them to drain effectuallyin the course shown by the arrows in Fig. 2. This is an important feature, as. there are no cocks to manipulate, yrequiring time and strict attention. The arrangement ofy the lateral pipes at an angle supplies a ,greater heating surface and the end connectionsv and joining means 18 provide-a methody for setting up and taking down any lateral without interference withl the others, as all are indeendent. The arrangement of the laterals facilitates caringy for the pipe when contraction or expansionoccurs in any part.

l lIt is possible to use all iron or `steel jin the metal parts, which makes a cheap construction. The combination of condensa- `to the floor and prevents fire risk. The

pipe and connections are all of common type `which is likewise economical.v

I claim- Y A heat radiating device, wherein is combined, a feed pipe, a dischargeA pipe positioned below the plane of the feed ipe, anda series of 'batteries of lateral pipes, each lateral pipe being'A independent and extending from a connection with the feed pipe at anangle .and inclinatiomto a connection, thence in a reverse angle andinclination to a connection with said discharge pipe, eachof saidlateral pipes being arrangedto allow effective drainagethrough the same, without auxiliary means therefor, and also to allow each lateral pipe and sections thereof ,to besecured, adjusted, ork

removed betweenconnections, independently of other pipes in sai-d radiating device.
